79 SRX Heat exchanger deleat question

[TerryR]

I race 660 ft snow drags on hard packed snow. Setting up the 79 SRX
to race without using a cool down cart. Want to defeat the tunnel exchanger only.
Anyone try this to comment on how well it works? Racing stock events that allows some alterations.

Parts listing makes it look like comes out of engine to rad then to
cooler then back to engine .. Looks like a hose from radiator to engine would fit.
My question is why . Maybe 8 lb involved . Expect you need clearance in track tunnel
for some nasty studs.
Are you allowed to add an extra rad even for more coolant ? as I expect some days you
will be shutting off so hot that when water pump stops circulating it could seize.
Just my thoughts .

Hi Ron. From your comment you have not tried this. Looking for anyone who has real world experience on this. Thanks. Looking at weight saving

Are you allowed to lighten the track ?
Hot knife off some of the track lug height and use shorter studs ? Shouldn't
damage the strength of the actual belting and will also reduce the torque
and power needed to spin it.
Try on another scrap track first to make sure they didn't add any belting up
into the lugs, expect they are pure rubber.
A friend said "try it, you will like it" . Went like stink !
When I returned the sled , he said I was the only one that still had it pinned past the finish marker
of the guys that tried it . Certainly hauled butt faster than my fluid drives.
Good luck , have fun and stay safe.

Would be good but I race on packed/not so packed snow .
